Simplifying x2 + -1.5x + -1.6875 = 0 Reorder the terms: -1.6875 + -1.5x + x2 = 0 Solving -1.6875 + -1.5x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '1.6875' to each side of the equation. -1.6875 + -1.5x + 1.6875 + x2 = 0 + 1.6875 Reorder the terms: -1.6875 + 1.6875 + -1.5x + x2 = 0 + 1.6875 Combine like terms: -1.6875 + 1.6875 = 0.0000 0.0000 + -1.5x + x2 = 0 + 1.6875 -1.5x + x2 = 0 + 1.6875 Combine like terms: 0 + 1.6875 = 1.6875 -1.5x + x2 = 1.6875 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 1.6875 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 1.6875 + 0.5625 Combine like terms: 1.6875 + 0.5625 = 2.25 0.5625 + -1.5x + x2 = 2.25 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 2.25 Calculate the square root of the right side: 1.5 Break this problem into two subproblems by setting (x + -0.75) equal to 1.5 and -1.5.Subproblem 1
x + -0.75 = 1.5 Simplifying x + -0.75 = 1.5 Reorder the terms: -0.75 + x = 1.5 Solving -0.75 + x = 1.5 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 1.5 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 1.5 + 0.75 x = 1.5 + 0.75 Combine like terms: 1.5 + 0.75 = 2.25 x = 2.25 Simplifying x = 2.25Subproblem 2
x + -0.75 = -1.5 Simplifying x + -0.75 = -1.5 Reorder the terms: -0.75 + x = -1.5 Solving -0.75 + x = -1.5 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -1.5 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -1.5 + 0.75 x = -1.5 + 0.75 Combine like terms: -1.5 + 0.75 = -0.75 x = -0.75 Simplifying x = -0.75Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.25, -0.75}
